Study on the rolling pressure of H-beam during rolling process

The distribution of the rolling pressure on H-beam is a very important problem. In this paper, the deformation processes of H-beam with different rolling parameters in the universal mill were simulated by explicit dynamic FEM, the main factors influencing the changing tendency of the rolling pressure of H-beam were obtained, and the reasons were also analyzed. The calculated results show that the influence of the flange width, the temperature, the inner width and the ratio of elongation between flange and web on the changing tendency of the rolling pressure of the web are significant. The influence of the flange width and the initial gauge of H-beam on the changing tendency of the rolling pressure of the outer side of the flange are significant.
